Effects of Tobacco Use

Tobacco Use-A Serious Health Risk

Smoking is the #1 cause of preventable disease and death in the US.

Many people begin using a form of tobacco in their teens, thinking that they can quit whenever they want. YOU CANNOT.

Nicotine

One reason that tobacco users find it hard to quit is because tobacco contains an addictive drug- a substance that causes physiological or psychological dependence.

All tobacco products contain nicotine- the additive drug in tobacco.

Nicotine is classified as a stimulant- a drug that increases the action of the central nervous system.

Nicotine raises your blood pressure, increases your heart rate, and contributes to heart disease and strokes.

Cigarette Smoke-A Toxic Mixture

Tobacco smoke was classified as a Class A carcinogen. (Then most deadly)

Carcinogen- a cancer-causing substance

Tar & Carbon Monoxide

Cigarette smoke contains tar- a thick, sticky, dark fluid produced when tobacco burns.

Tar damages lungs and eventually burns holes in them, making it impossible to breathe.

Carbon Monoxide- a colorless, odorless, and poisonous gas.

Carbon Monoxide Prevents oxygen form getting to cells.

Harmful Effects of Pipes and Cigars

Cigars contain significantly more nicotine and produce more tar and carbon monoxide than cigarettes do.

1 cigar contains more nicotine that a whole pack of cigarettes.

Harmful Effects of Smokeless Tobacco

Smokeless Tobacco- tobacco that is sniffed through the nose, held on mouth, or chewed.

Because smokeless tobacco is held in the mouth for a length of time, it delivers nicotine and carcinogens that can be 2 – 3 times MORE than a cigarette.

As a result, smokeless tobacco can cause leukopkia- thick, white, leathery spots on the inside of the mouth that develop into cancer.

How Tobacco Affects the Body

students smoke, that is down from 36% of students who were smoking in 1997.

Preventing Tobacco Use

The best way to avoid tobacco is to never use it.

Nearly 90% of all smokers started in their teens, so if you do not start smoking in middle or high school you are much less likely to smoke later in life.

These are strategies to remain smoke and tobacco free:

Choose friends who don’t smoke.Avoid situations where tobacco

products may be used.Practice and use refusal skills.

Why Teens Choose to Use Tobacco

They think it makes them look older.They feel independent.Peer pressureParental influence

Stopping the Addiction Cycle

Most people who choose to be healthy and quit using tobacco usually experience nicotine withdrawal- the process that occurs in the body when nicotine is no longer needed.

The cravings and discomfort caused by withdraw are temporary.

Symptoms of withdraw include:

IrritabilityDifficulty concentratingAnxiety Trouble sleeping

To relieve the symptoms some people use a nicotine substitute- a product that delivers small amounts of nicotine into the user’s system while he or she is trying to give up the tobacco habit.

alternativesChange daily behavior

Lesson 3Promoting a Smoke-Free Environment

Risks for Smokers and Nonsmokers Environmental tobacco smoke (ETS)- secondhand

smoke- air that has been contaminated by tobacco smoke.

ETS is composed of mainstream smoke- the smoke exhaled from the lungs of a smoker & sidestream smoke- the smoke from the burning end of a tobacco product.

Sidestream smoke is more dangerous than mainstream smoke because it has higher concentrations of carcinogens, nicotine, and tar.

Effect of Smoking on Unborn Children

Smoking while pregnant can cause many fetal problems: miscarriage impaired fetal growth low birth weight premature delivery still born

Once the child is born they still may face many health problems:

asthma tonsillitis respiratory tract infections

Children who live with smokers have double the risk of developing lung cancer than children of nonsmokers.

Reducing Your Risks

When someone lights up in front of you, politely ask him or her to smoke somewhere else.
